Low-power-consumption positioning method and related apparatus

A positioning system, comprising:

• an electronic device configured to:
• receive a first input;
• send first setting information in response to the first input;
• and
• send first GNSS location information;
• and
• a server configured to:
• receive the first setting information and the first GNSS location information from the electronic device;
• set, using the first setting information, a time interval at which the server broadcasts positioning assistance data as a first time interval;
• determine first positioning assistance data based on the first GNSS location information and first measurement data reported by N reference stations, wherein N is a positive integer;
• and
• broadcast the first positioning assistance data to the electronic device at the first time interval, wherein the electronic device is further configured to:
• resolve first high-precision positioning information based on the first GNSS location information and the first positioning assistance data;
• send, when the electronic device detects that the electronic device meets a first preset condition, second setting information to the server;
• and
• send second GNSS location information to the server, wherein the server is further configured to:
• set, using the second setting information, a time interval at which the server broadcasts positioning assistance data as a second time interval, wherein the second time interval is longer than the first time interval;
• determine second positioning assistance data based on the second GNSS location information and second measurement data reported by the N reference stations;
• and
• broadcast the second positioning assistance data to the electronic device at the second time interval, and
• wherein the electronic device is further configured to resolve second high-precision positioning information based on the second GNSS location information and the second positioning assistance data.
